Whether a material comprises valuable cargo being transported following the classic Mt. Everest expedition trail or comprises waste material being transported from the backyard to the local dump, containing and transporting the material poses a variety of problems familiar to the ordinary person.
One familiar problem related to containing and transporting material can be the difficulty of containing material amassed or accumulated on conventional tarpaulins or similar flexible sheets (“conventional tarpaulins”). Because conventional tarpaulins can be laid flat for efficient loading of material(s), a numerous and wide variety of devices and methods have been developed to gather or secure opposed portions of the tarpaulin periphery in an attempt to contain the material loaded. For example, cords, straps, or similar elements threaded through holes or grommets in the periphery or corners of the tarpaulin have been used to gather portions of the periphery of a tarpaulin as described for example by U.S. Pat. Nos. 2,766,799, 3,024,824, and 5,943,831; alternately cords attached to the periphery or the corners of the tarpaulin can be tied together to gather portions of the periphery as described for example by U.S. patent application Ser. Nos. 3,355,187, 4,519,183 and 6,267,504; and opposed parts of self-securing adhesive strips or hook and loop fabric fixed to the periphery of the tarpaulin can be joined as described for example by U.S. Pat. Nos. 4,620,396 and 5,364,188 to gather portions of the tarpaulin periphery.
Similarly, numerous and varied devices and methods have been developed for moving conventional tarpaulins on which material has been amassed or accumulated which do not address closure of the periphery of the tarpaulin prior to movement as described for example by U.S. Pat. Nos. 5,147,102; 5,529,321; 5,660,402; 6,565,101; 5,104,133; and 4,173,351.
As to each of these varied devices and methods of containing or transporting material on an open or within a gathered conventional tarpaulin, there is a common problem in that no attempt to close the tarpaulin has been made or only a portion of periphery of the tarpaulin has been drawn upon or joined to contain the material loaded. As such, a substantial portion of the periphery of the tarpaulin may remain open allowing material to egress from the tarpaulin or conversely may remain open allowing ingress of other material into the tarpaulin. In any event, none of these devices or methods of containing material on or within a tarpaulin address the need of closing substantially the entirety of the periphery of the tarpaulin to decrease the transfer of material(s).
Another familiar problem with the use of conventional tarpaulins or other conventional devices which initially lay flat for loading and then alter configuration by coupling or joining portions of the periphery can be that a plurality of discrete closures must be operated to generate the closed condition of the device. This approach is utilized for example by the devices described by U.S. Pat. Nos. 2,254,578 and 3,073,367 each of which utilize four discrete zippers to generate the particular closed configuration. As such, these types of devices may be overly complex or incompatible with containing and transporting cargo or waste materials, or may not operate or may not be practical to operate to generate the closed configuration on the scale necessary to contain the amount of material generally amassed on the conventional tarpaulin.
Moreover, these and other conventional types of devices which have many discrete closures or even a single closure such as a zipper can be prone the egress and ingress of materials through the closure elements such as fine particulates and liquid. As can be understood by U.S. Pat. Nos. 2,254,578 and 3,073,367, as examples, neither conventional device affords any protection against the transfer of material through the plurality of discrete zippers.
Another familiar problem with the use of conventional tarpaulins or other conventional devices which initially lay flat for loading can be that the closure operates to join portions of the periphery of a device to establish a substantially vertical container wall relative to the support surface. For example, U.S. Pat. No. 4,604,765 describes a conventional device which joins adjacent portions of the periphery of a square material by substantially vertical operation of the closure relative to the support surface.
In the case of a conventional tarpaulin where a substantial amount of material can be amassed or accumulated the person may have to bend over to operate the closure, a closure that operates vertically for more than a few inches relative to the support surface may require the person to move the entire body from the bent over position to the upright position to generate the closed condition of the container. Additionally, when a person is in the bent position the forces applied to the closure element may not be directed vertically, but rather the predominant direction of the force applied to the closure may be between the plane of the support surface and the vertical plane of the closure. As such, more overall force may have to be applied to the closure to generate the closed condition of the material container.
Another problem with conventional tarpaulins or other conventional devices which initially lay flat for loading can be a lack of means to substantially fix the location of the tarpaulin during closure operation. Again referring to U.S. Pat. No. 4,604,765, the force of operating the closure in the vertical direction may lift the device from the support surface. Again, in those instances in which the person may be using one hand to hold the portions of the periphery to be joined and one hand to operate the closure, movement of the material container can occur because there is not way to restrain it.
Overall conventional tarpaulins do not appear to disclose a device which lays flat in the open condition for amassing or accumulating materials thereon and provides an open configuration operably coordinated with the range of motion of a person bent over to commence operation of the closure. This lack of a posture coordinated planar configuration may be apparent with respect to the operating angle of the closure relative to angle of a person's body bent to commence operation of the closure, and also with respect to the location of grips and restraints relative to the location of the persons feet or hands in the bent over position, or both.
The instant material containment invention addresses each of these problems related to conventional tarpaulins and containment devices.
II. SUMMARY OF THE INVENTIONAccordingly, a broad object of the invention can be to provide a material container which provides a flexible layer which can be established in a substantially planar configuration on a support surface for loading material and which operably conforms by closure to provide an enclosed space to contain the loaded material.
This broad object of the invention can include particular embodiments of the material container invention which operably conform through the use of a single closure element to provide the enclosed space defined by joining substantially the entirety of the periphery of the flexible layer established in the substantially planar configuration in the open condition.
Another broad object of the invention can be to provide a material container which provides a flexible layer which can be established in a posture coordinated planar configuration on a support surface which operably conforms by closure to provide an enclosed space to contain the loaded material.
This broad object of the invention can include particular embodiments of the material container invention which include a flexible layer having a square or rectangular body coupled on at least one of the opposed sides by a triangular end portion the vertices of which can be held in a first hand adjacent to one another to position a closure element to commence operation at the apex of the triangular end portion located proximate to the support surface. Another benefit of the triangular end portion can be to locate the closure element at an angle from the support surface between about ten degrees and about 45 degrees to accept a greater portion of the directional forces applied by a person operating the closure in the bent position with a second hand. Additionally, the apex of the triangular end portion can provide the further benefit of locating a restraint element for engagement by the foot of the person to fix the location of the closure element during operation. By configuring the substantially planar configuration of the flexible layer of the material container invention to operate in coordinated fashion with the anatomical range of the person's hands and feet, generation of the closed condition of the material container invention can be achieved with greater efficiency and less effort.
Another broad object of the invention can be to provide a closure cover which operates in a first condition to protect the closure element in the closed condition from the ingress of solids or liquids and in a second condition provides sensorially perceivable indicia that the closure cover requires adjustment to protect the closure from ingress of solids or liquids.
Naturally, further objects of the invention are disclosed throughout other areas of the specification, drawings, and claims.

The person can take the further steps of operating a closure cover (29) coupled to the flexible layer (26) between the first apex (16) of the first triangular region (17) and the second apex (18) of the second triangular region (19) in a manner which allows the closure cover (29) to operably locate over the closure element (15)(as shown by
As shown by
Now referring primarily to
Also it is to be understood that the term “substantially planar configuration” and the particular embodiments of the “substantially planar configuration” shown by the figures are not intended to limit the material container (2) invention solely to those embodiments of an open condition of the material container (2) in which the flexible layer (26) is established in a single plane, but rather broadly encompasses a wide variety of alternate configurations of the flexible layer (26) which would ordinarily occur when a flexible layer is laid open for loading as described, and specifically includes without limitation, those configurations of the flexible layer (26) generated in the open condition due to: the topography of the underlying support surface (4), variation in the flexible layer material, variation in production steps such as unequal tensioning of the flexible layer due to joining, stitching, bonding, or the like, subsequent use of the flexible layer which may stretch or otherwise deform the flexible layer (26), or similar variations, and further includes depending upon the embodiment of the invention, the closure element (15), the flaps (6) which operate between a position extended outward to traverse over the closure element (15) (as shown for example by
Now again referring primarily to
The parts of the closure element (15) can be coupled to substantially the entirety of the periphery of the substantially planar configuration (3) to commence operation proximate to the first apex (16) of said first triangular end portion (17) and to terminate operation proximate to the second apex (18) of said second triangular end portion (19), thereby generating an amount of enclosed space (20) in the closed condition of the material container (2).
The first triangular end portion (17) can establish a first angle “x” (38) between a base (shown in hash marked line) of the first triangular end portion (17) and a first leg of the first triangular end portion (17) and can establish a second angle “y” (39) between the base (shown in hash marked line) of said first triangular end portion (17) and a second leg of the first triangular end portion (17). Typically the first angle “x” (38) and the second angle “y” (39) are of similar or of substantially the same angle which can vary depending upon the embodiment of the material container (2) invention between about ten degrees and about forty five degrees.
Similarly, the second triangular end portion (19) can establish a first angle “w” (40) between a base (shown in hash mark line) of said second triangular end portion (19) and a first leg of said second triangular end portion (19) and a second angle “z” (41) can be established between the base (shown in hash mark line) of the second triangular end portion (19) and a second leg of the second triangular end portion (19). Again, typically, the first angle “w” (40) and the second angle “z” (41) are of similar or of substantially the same angle which can vary depending upon the embodiment of the material container (2) invention between about ten degrees and about forty five degrees.
The amount of angle established by the first angle “x” (38) and the second angle “z” (39) of the first triangular end portion (17) and the first angle “w” (40) and the second angle “z” (41) of the second triangular end portion (19) can each independently or in combination alter force characteristics with respect to operation of the closure element (15) to generate the closed condition of the material container (2). Altered force characteristics can comprise a reduction in the amount of force to operate the closure element (15) between the first apex (16) of the first triangular end portion (17) and the second apex (18) of the second triangular end portion (19) whether in whole, or as to a particular portion of the operation; or altered force characteristics can comprise an alteration in the vector forces as received by the material container (2) or as applied by the person (1) operating the closure element (15), or both.
Altering the vector forces as received by the material container (2) or as applied by the person (1), can significantly reduce efforts by the person (2) to commence operation of the closure element (15), to terminate operation of the closure element (15), or to establish the material container (2) in the closed condition, even in those instances where there is no reduction in the overall amount of force utilized to generate the closed condition of the material container (2).
In addition, with reference to
Moreover, configuring the planer configuration (3) to include the first triangular end portion (17) and the second triangular end portion (19) provides a portion of the flexible layer (26), otherwise lacking, which disseminates force imposed by the material (5) contained within the enclosed space (20) over a greater surface area proximate to the ends of the material container (2) in the closed configuration.
Although the examples of the material container (2) shown by the drawings each show a first triangular end portion (17) and a second triangular end portion (19) certain embodiments of the material container (2) invention may include only the first triangular region (17) or only the second triangular region (19), or with no triangular end portion (but otherwise benefiting from other inventive elements described herein), the closure element (15) configured accordingly.
